Just last week, Kirk Hinrich fielded questions about being one of the few Bulls not to miss a game because of injury this season. But in a mind-numbingly regular occurrence, the Bulls incurred another setback Saturday when Hinrich sat out with a bad back. "He just said it stiffened up on him," coach Tom Thibodeau said. "Hopefully, it won't be anything that lasts long." Hinrich, who missed 22 games last season because of a variety of injuries, had snapped out of a miserable shooting slump Friday in Milwaukee with 13 points and eight assists. Hinrich wasn't made available to reporters before Saturday's game. "When you look at managing the minutes, sometimes when you have older players, you look into it more," Thibodeau said. "We've done a good job with that. We had Rip (Hamilton). We have Carlos (Boozer). We keep their minutes down. Guys that are younger, they play more. If you're a starter, you're expected to play 32 to 36 minutes." Point taken: Hinrich's injury continued the strange saga of Marquis Teague, who had been supplanted as the backup point guard by veteran Mike James and banished to the Development League before James sprained the MCL in his right knee.
